(a)[1]
State why force is considered a vector quantity.
(b(i))[1]
Calculate the greatest possible force on the object from these two forces.
(b(ii))[2]
Calculate the acceleration produced by a resultant force equal to this maximum force.
(c)[3]
In the space below, draw a scale diagram to find the resultant velocity of the swimmer relative to the river banks. This velocity is the resultant of the two velocities shown in Fig. 1.1. Put a label on the resultant in your diagram.
